Ive got an oops, which is heavy with <symbol-addres> + <hex/hex> offsets?

problem is, objdump doesnt render with that convention, so mental math
is necessary to find lines.
000003c4 <sysfs_hash_and_remove>:
3c4: 55 push %ebp
3c5: 89 e5 mov %esp,%ebp
3c7: 57 push %edi
3c8: 56 push %esi
It would be nice if it instead showed
000003c4 <sysfs_hash_and_remove>:
+000: 55 push %ebp
+001: 89 e5 mov %esp,%ebp
+003: 57 push %edi
Is there a way, that Ive missed rtfm'g, to make objdump output and
kernel-oopses correspond obviously ?
